Mysterious asterism effect!
Black star sapphire 7.65 ct

RECOMMENDED POINTS
Enjoy the impressive large grains.

Black star sapphire that gives you a sense of the mystery of nature!
When exposed to strong light from one direction
A star suddenly appears.

Something as simple as a smartphone light
It will be something you can see stars in.

The mysterious asterism of this black sapphire
It is not due to silk inclusions,

Due to the inclusion of hematite (iron oxide)
This is due to the effect of light on the lamellar structure.

When the spotlight is shone on it, the Rokujo Star appears.
Body color like the night sky, the appearance of stars
Everyone will be surprised.

A beautiful and bold star, like a star floating in the night sky.
Enjoy this beautiful moment.

*Star stones are evaluated after only the surface is polished.
The sides and back are not polished, leaving them in a natural, uneven state.
Thank you for your understanding in advance.
